SPINNING-RING COUPLER.

SPECIFICATION forming part of Letters Patent No. 459,255, dated September 8, 1891.

Application filed May 21, 1891. Serial No. 393,603. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES MCCARTY, of Fall River, county of Bristol, State of Massachusetts, have invented an Improvement in Spinning-Ring Couplers, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on thedrawin gs representing like parts.

IV hen changing a spinning-frame from warp to weft yarn, it is necessary to employ smaller rings. IVhen this change is to be effected, it is customary to take the rings and their holders from the rail and substitute a new set of rings of smaller diameter, they being held in holders adapted to fit the rail. These new rings have to be adjusted to the spindles, the whole process consuming much labor and keeping the frame unproductive.

To avoid this waste of time in taking ofi rings and applying and adjusting others is the object of this invention; and to enable the frame to be changed from warp to filling winding quickly I have devised a coupling adapted to embrace or engage and hold the lower race of the ring to be applied and also to be engaged and be supported by the upper end or race of the ring then connected with the rail, the ring so added being superimposed upon the former ring, the superimposed ring being of smaller diameter.

Figure 1, in top View, shows part of a ringrail with my invention added. Fig. 2 shows the rings at the left in Fig. 1 in section in the dotted line y, the rings at the right being in elevation. Fig. 3 is a section in the line 00, Fig. 1. Fig. l is a section of a modified form of coupling shown as holding two rings, and Fig. 5 shows the coupling in plan View detached.

The rail A has a series of holes a, adapted for rings Z), which are retained in place by holders 0, secured to the rail by screws 0, all as usual. Now let it be supposed that the rings 1) are being used and the frame operated to wind bobbins for warp and that it is desired to alter the frame to wind filling. To do this, instead of taking off the rings Z) by detaching their holders from the rail I take a series of smaller rings (Z and by means of a coupling secure the said rings to the rings Z).

The coupling represented in Figs. 1, 2, and 3 is composed of a sheet-metal ring 6, having portions of its inner edge struck up to form lips 6 (see Fig. 2) and portions of its outer edge to form lips e (See Figs. 1 and 3.) A coupling of this kind may be made to embrace or hold part of the lower race of the ring d by the lips e, while the lips e embrace the upper end of the flange or race of the 6:

ring I).

In the modification, Fig. 4, instead of em ploying a sheet-metal coupling having its opposite side edges overturned to form lips I employ a coupling it, made as a ring split at the exact construction shown for the ringcoupling, as prior to my invention I am not aware that any provision has ever been made to enable a ring of one diameter to be operatively supported upon a ring of another diameter to thus enable a spinning-frame to be So changed to wind at times warp and at other times weft bobbins.

I claim- 1. A. coupling for spinning-rings of differ ent diameter, consisting of a ring having inwardly-turned lips upon portions of its inner edge and oppositely-turned lips upon portions of its outer edge adapted to engage flanges of two superimposed rings, respectively, and unite them operatively, substano tially as described.

2. The rings (1 and I), combined with a ring coupling having lips to engage the upper flange of ring Z1 and the lower flange of ring d to thus unite the said rings, as and for the 5 purpose set forth.

This ring- 70 3. A ring-rail, a spinning-ring of one diname to this specification in the presence of ameter connected thereto, andasuperimposed two subscribing witnesses. ring of a different diameter, combined with a {*1 I 1 coupling to unite one of said rings to the other UHARLEb MCCARTY' 5 of said rings, to operate substantially as de- WVitnesses:
